“Ye Cannot Know of Things Which Ye Do Not See”

Joseph F. McConkie, Robert L. Millet
This position is a radical form of empiricism, a pure naturalism. To state it in another way: “If I cannot see it, it does not exist. I can only deal with that which is seen or felt or heard by the physical senses.” From the world’s perspective, seeing is believing. From the gospel perspective, believing is seeing.
